"the Schedule referred to in these Letters Patent and making part of the same To all persons luau/ om these presents may come:

Be it known that- I, Susanne M. S'roox nn, of

Georgetown, of the county of Essex and State of .fully described in the following specification and represented in the accompanying drawing, of which- Fignre 1 denotes a front elevation of a presserfoot and a feeder of a "sewing-machine, as recessed in accordance with my-invention.

F ignre 2 is a top y'iew of the feeder, and

Figure 3, a bottom view of the presser-foot.

Figure 4; is a top view of the feeder, as'recessed on one side only of the needle-slot.

Figure5 is an under-side view of the presser-foot, as sil'nilarly recessed,

In carrying out my invention I form in the presserfoot a notch or recess, to extend from the needle-Slot, latelally, either to one or both of the opposite edges of the foot, and I also form another notch or recess in the fcederin suhstantiallythe same manner.

In the drawing- A denotes the 1n'esser-li)ot,-ahd

B the feeder, denoting the needle-slot in the one, till] bthat in the other;

The recess of one is exhibited at c, and that-of the ither at If. 7

Figs. 2 and?represcnt'these recesses as extending entirely across the two articles, while figs.z4' and.- 5

, 'epresent such recesses as opening out of oncside mly of the needle-slots.

The recess of the feeder is sunk downward from its toothed or notched surface.

presser-foot will enablethe work to he turned only to the right or to the left, according as the notches may be arranged; but by extending the notch or recess entirely across the feeder, and also entirely across the presser-foot, .the work can be turned either to the right or to the left wither-rt the stitch becoming clamped or pinched, so as to be prevented from being drawn closely into the work. a

I am aware that the feeder of a sewing-machine has been grooved, dented, or serrated for the purpose of enabling it to properly act on the work for advancing [it or feeding it along, such forming no part of my invention, which involves the employment of notches or recesses, to extend entirely, below the teeth or holding-grooves or devices. ofthe upper surface of the feeders.

I would remark that my improvement is designed especiallyfor chain-stitch sewing-machines, in which an aw] 'and a needle are employed, such machines being designed for the sewing of leather, The wellknown Whittemore machine, of this nature, is one is peculiarly appropriate, and on which .I have employed it to great advantage.

The recesses of the feeder and the p'resser-foot are to be so arranged, w'itl1 reference to the needle, as to The presser-foot and feeder, provided with the stitch-. receiving recesses, arranged with reference to their needle-slots, and so as to extend therefrom laterally out of the feeder and presser-foot, as and for the purpose as hereinbefin'e' explained.
